CAUTION: The Sender of this email is not from within Dalhousie. Dear Colleagues, The workshop on “Higher structures and operadic calculus” will take place at the CRM (Barcelona) from June 21 to June 25, 2021: https://www.crm.cat/higher-structures-and-operadic-calculus/ <https://www.crm.cat/higher-structures-and-operadic-calculus/> . It will be organised in an hybrid format so if you miss blackboard talks and human interactions, feel free to join us there, if you cannot travel, you will be able to follow the lectures online. The idea of this workshop is to provide the audience with a state of the art of these domains, which enjoy currently rapid developments, through the following five courses. “Higher structures in rational homotopy theory” by Alexander Berglund (Stockholm University) “An operadic view on associators” by Damien Calaque (Université de Montpellier) “Operadic deformation theory” by Ricardo Campos (CNRS, Université de Montpellier) “Weight structures and formality” by Geoffroy Horel (Université Sorbonne Paris Nord) “Infinity modular operads and the Grothendieck—Teichmüller group” by Marcy Robertson (University of Melbourne) If you are interested, please register on the webpage of the workshop. Further details can be found there. Detailed notes of the lectures will be typed and made available after the workshop. Yours, Bruno --------------------------------------- Professeur Université Paris 13 Laboratoire Analyse, Géométrie et Applications (LAGA) www.math.univ-paris13.fr/~vallette/ [For admin and other information see: http://www.mta.ca/~cat-dist/ ]
